On Monday, 24-year-old Canadian soldier Megan Cuoto made history on her first trip to London. As the leader of her unit — invited to the U.K. in honor of Canada’s 150th anniversary — Cuoto became the first woman to ever lead the historic Changing of the Guard ceremony outside Buckingham Palace.

“I’m just focusing on doing my job as best I can and staying humble,” Cuoto told The Associated Press, “Any of my peers would be absolutely delighted to be Captain of the Queen’s Guard and I’m equally honored.” The role of Mounting the Queen’s Guard has traditionally fallen to the British Army’s Household Division, a unit mostly comprised of men.
